12.  def localOutlierFactor(dataframe: DataFrame, k: Int = 20, geometry: String = null, handleTies: Boolean = false, useSpheroid: Boolean = false): DataFrame

    Annotates a dataframe with a column containing the local outlier factor for each data record.

    Annotates a dataframe with a column containing the local outlier factor for each data record. The dataframe should contain at least one GeometryType column. Rows must be unique. If one geometry column is present it will be used automatically. If two are present, the one named 'geometry' will be used. If more than one are present and neither is named 'geometry', the column name must be provided.

    dataframe

    dataframe containing the point geometries

    k

    number of nearest neighbors that will be considered for the LOF calculation

    geometry

    name of the geometry column

    handleTies

    whether to handle ties in the k-distance calculation. Default is false

    useSpheroid

    whether to use a cartesian or spheroidal distance calculation. Default is false

    returns

    A DataFrame containing the lof for each row
